Application iled February 4, 1905. Serial No. 244,209.

T0 all whom it may concern:

Be it known that I, WILLIAM H. GOLDING, a citizen of the United States, residing lat Newton, in the county of Middlesex and State of Massachusetts, have invented new and useful Improvements in Printing-Presses, of which the following, taken in connection with the accompanying drawings, is a specification.

My invention relates to the parts of a printing-press which are functionally connected with the movements of the sheets of paper after they have been placed upon the platen and also with their movements in being transferred from the platen to the receiving table or board. 7'

The mechanical features involved in the inventionare fully explained in the following description and the accompanying drawings.

The drawings consist of a number of figures, of whichy Figure l is a side elevation of a printingpress of the type to which I apply my improvements. The parts that are not in some manner connected to or related to my new devices are omitted. Fig. 2 is a plan view of the parts required in the explanation of my invention. Fig. 3 shows in front elevation some of the more essential features. Figsxl, 5, and 6 are enlarged views of details relating to the device for removing the sheets from the platen and depositing the same on the' delivery-table. Figs. 7, 8, and 9 are enlarged views of parts relating to the device for adjustin the sheets for printing and for moving them into the field of action of the sheet-removing device. Figs. 10 and ll show in elevation and plan some of the details connected flith the devices for moving the delivery-ta- In the drawings the base of machine and other fixed parts are indicated by the letter A and A with attached numerals.

i `The main driving-shaft is' indicated by B, which drives the inion B and through it the gear B2 and t e other parts of themachine. A cam C is allixed to the gear B2 and serves to givemotion to the rocker-shaft C13 through the cam-roller T2, lever C3, pivoted at C1, adjustable link C6 C8 C7, Fig. l, pivot-pin C, and rockerarm C10, Fig. 2, the said rocker-arm C10 being adjustably attached to the rocker-shaft C13 by the clamps C11 and screw C12. A long swinging arm D is attached to the rocker-shaft C12v and carries at its outer end the sheet-gripping device F2 F7, moving it forth and back 1n the arc S, Fig. 2. The rocker-shaft C13 is journaled in the parts A3 A5 of the frame of the press. A second arm D3, parallel to the arm D, is pivoted to the fixed part A1, extending from A3, (see Fig 2,) and is connected at its outer end by the link D2 to the outer end of the arm D and serves to hold the gripper in line with the platen.

I will now describe the gripper and lits connected parts, as particularly -illustrated in Figs. 4, 5, and 6. A flat extension d extends from the end of the arm D and hasaflixed in it a bolt D', which cannot rotate in the extension d, but is made round, so that. the link D2 can swing freely upon it as the arms `D and D3 swing in the arc S. (See Fig.y 2.) A cylinder D5, connected to the link D2, serves as a casing or housing for the swiveling parts of the gripper. A pulley F11 is attachedto the bolt D', but does not turn yon--that is, it is stationary in relation to the arm D; ybut the link D2 swings about it as a center when the parallels D and D3 swing forth and back, thus causing the cord F10 to operate the pulley F thereby turning the grippers F7 F, which are mounted on the spindle F about their longitudinal axis. The lower jaw F6 of the grippers is made as a part of the pulley F. land `spindle F, and the upper jaw F7 of the grippers is pivoted at F8 to the said lower jaw F6. The said pivot F8 is rigidly attached to the jaw F7, but free to turn in jaw F6. -The said pivot F8 has an arm F12 inserted in it. The said arm F12 is so placed that when theparallels D and D3 swing outward, as indicated by the arc S, it comes in contact with the adjustable rod F13 on the bracket A8 (see Fig. 3) and is thrown forward, causing the pivot-pin F8 (see Fig. 4) to make `a part rotation, and thus throw the clamping-j aw F7 upward, (see dotted lines, Fig. 6,) releasing the sheet of-,paper held between the jaws F6 and F7. v

When the gripper is carried back to the platen, it still remains open until it is in position to seize the printed sheet lying upon the platen. In this position the arm F12 comes in contact with the end of thearm F14, which is attached to the eccentric-shaft P. (See Figs. l and 2.) This eccentric-shaft is of ordinary construction and serves to operate the platen P in the usual manner, and is thrown backward, so as to turn the` pivotpin F8, andy thus close Vthe jaw F.7,grasping- TOO IIO

the Said printed sheet, and at the next movement of the parallels D and D3 take the sheet over to the delivery-table H11. The gripper is so adjusted that the plane of its jaws coincides with the plane of the platen when about to take the sheet, but as the said gripper retreats with the sheet of paperl it is turned by the spring F2, which will act as soon as the cord F10 is slackened by the swinging of the link D2, as has been explained.

To hold the gripper open or closed at the right time, the following-described device is used: A V-shaped projection F15 is formed on the end of the moving jaw F7 and is adapted to engage with a similar projection on the end of the sliding bar F3, which is forced outward by the spring F1. (See Fig. 6.) A mechanism for moving the sheet into the field of action of the gripper is connected with the registering device, which will be hereinafter explained.

To prevent the arm F14 close the gripper when the impression is not being made, it is thrown back by turning the eccentric-shaft P by the handle P2-that is, the same movement of the eccentric-shaft that moves the platen away from the printing-plate also throws the arm F14 out of action with the gripper.

The delivery-table H11 is moved forth and back longitudinally, but step by step, as the printed sheets are placed upon it, whereby the printed sheets are distributed evenly throughout the length of the table and are better placed for drying and for preventing offset. The said table is supported upon tilting brackets H4, which are made fast to the rod H7 by setscrews, one of which shown at H8, Fig. 10. The rod H7 is held loosely in bracket-arms H3, which are formed on the sliding bar H3. A spring H10 is attached at one end by a screw (see Fig. 11) to the rod H7 and engages at its other end with the bracket-arm H6 and is so arranged that its tendency is to throw the left-hand side of the table down, as shown in full lines in iFig. 10, the projection h resting upon the top of the slide H3. When desired to remove the sheets from the table, it may be tilted, as indicated by the dotted lines in Fig. l0. The slide H3 is constructed to move forth and back in the way-piece H', which is held by screws H2 to the bracket-pieces H, which are firmly secured to the fixed rod A7. The slide H3, that causes the delivery-table H11 to traverse, is provided with ratchet-teeth H3, which are acted upon by the double-acting pawl K5 K4, which is pivoted to the headblock K3 by the pin K3. (See Fig. l1.) The head-block K3 is connected to and operated by the rod K2. (See Figs. 11, l, and 2.) The rod K2 is operated by an eccentric K on the rocker-shaft C13 and is connected to the said eccentric by an eccentric-strap K. The pawl K1 K5, Fig. 11, is so constructed that either from operating to of its two ends may be in working relation to the ratchet H5 and is held in either of the positions by the V-shaped projection K10 engaging with the yielding block K11, which is controlled by the spring K12. The double pawl K4 K5 is tilted by the boss K7 coming in contact with one of the buttress-pieces K3 K2, one of which, K3, is shown in Fig. 11, and the other, K3, is shown in Fig. 2.

The sheet moving, adjusting, and holding device is illustrated in Figs. 2, 7, 8, and 9. In these drawings, R and R2represent clamping-fingers which are adjustably attached to the rocker-shaft R by thumb-screws R. The rocker-shaft R is of ordinary construction and is adjusted in the usual n'ianner.

The clamping-finger R-th,at is, the fniger most remote from the delivery-table-has a longitudinal slot R10, Figs. 7 and S, which is made for the purpose of making room for the sliding gage-iinger G. This gage-finger G has a clip Gfor the purpose of assisting in holding the sheets and is connected to a quill G, which is mounted on the quill R11, which can be moved longitudinally on the rocker-shaft R. The said quill R11 serves as a journal for said uill G3 to slide upon. The said second quill 13 has arms G4 G3, which have inclined terminals, as shown, which are constructed to operate with the similar inclines on the arms R7 R3, connected with the clampingfinger R. A spring G3, attached to the collar R3, (fixed to the quillR11,) serves to hold the moving gage-fmger G down onto the platen and also to push the said gage G back on the platen a little removed from the place on the platen P that would be occupied by the edge of the sheet to be printed. When the clamping-finger Ris raised up, as indicated in Figs. 7 and 9, then the moving gage G is forced back away from the position at the edge of the sheet to be printed; but when the clampin -iinger R is coming down to its sheethdiding position, as shown in Fig. S, then the moving gage G is forced forward (by the inclines R7 and R3 acting on the inclines G4 G3) against the edge of the sheet to be )rinted and in its forward movement forces tlhe said sheet into the exact position for printing and also into the field of action of the gripper F7 F1.

The clamping-iinger R has attached to it an auxiliary adjustable arm R, held by a thumb-screw R4, which works through a slot R3. (See Figs. 7 and S.)

The outer edges of the clamping-fingers R R2 are serrated for the purpose of retainingl sheet-holding cords in any desired places.

The rocker-arm C13, which operates the rocker-shaft C13, is operated bv the adjustable link C C3 C7, thereby regu ating the extent of movement of the gripper-frame and the gripper and insuring the gripping of the paper at the desired point.

The rod F13, which opens the gripper, is ad- IOO justable on the arm A8 both as to its length and position, so that it may always be in position to open the gripper. AbulIerAD, made of leather or some other suitable material, is attached to the arm A8, Fig. 3, and is intended to receive the stroke of the gripper-swing-ingI frame vand check it without shock.

Although I have shown in the drawings and described in the specification the regstering-gage and its connecting parts, also the serrated-edged clamping-finger and its functionally connected part, and the peculiar means for operating the delivery-table and the delivery-table itself, I do not claim them in this application, as I reserve the subjectmatter involved in these parts for separate application.
